The official tally of storm-related deaths across Texas rose to 131 on Monday as authorities warned of yet another round of heavy rains 10 days after a Hill Country flash flood that transformed the Guadalupe River into a killer torrent.

At least a further 166 remain missing, with officials fearing the death toll could soar. Twenty-seven young girls and staff members were killed at Camp Mystic, an all-girls Christian summer camp situated on the bank of the Guadalupe River.

Officials kept a wary eye on river levels as some crews resumed the search for people still missing after catastrophic flooding pummeled Texas this month.

Emergency crews have suspended their search for victims of catastrophic flooding in central Texas amid new warnings that additional rain will again cause waterways to surge.

More than 130 people are dead after devastating flooding in the Texas Hill Country that began early on the Fourth of July.
